How to use DB in Browser
Load CSVs as SQLite tables, run SQL joins, copy results as CSV/TSV/JSON. Follow these steps to get a reliable result in seconds.
- 1
Drop a CSV file (or paste CSV) and create a table — repeat to add more tables.
- 2
Write SQL in the editor and press Run (Ctrl/Cmd+Enter). Use sample chips for preview, count, and join queries.
- 3
Review the result table with timing and row counts.
- 4
Copy the result as CSV, TSV, or JSON, or download it. Reloading resets the in-memory database.
Common use cases
Practical ways people use DB in Browser on RividTech.

DB in Browser FAQs
Quick answers about privacy, limits, and how this tool works.
Which database runs in my browser?
SQLite (via the sql.js WebAssembly build). CSVs become tables with inferred INTEGER, REAL, or TEXT columns, and you can query them with standard SQLite SQL including JOINs.
Do my tables persist after reload?
No. The database is in-memory only — reloading the page starts a fresh session. Export anything you need as CSV, TSV, or JSON first.
Is DB in Browser free to use?
Yes. DB in Browser on RividTech is free, with no account or signup required.
Is my data uploaded to a server?
No. Processing runs entirely in your browser. RividTech does not upload your file contents for conversion or cleaning.
Is there a file size limit?
Limits depend on your device and browser memory. Very large files may run slowly; try Sample Data or Split CSV for huge datasets.
